Printer Won't Connect to Network

   As explained above, that's a modem, not a router.  Are you using the
same router as before (WNDR4300)?  Did you change any of the
configuration of the WNDR4300?  ("WNDR4300" or "WNDR4300v2"?  Look at
the product label on the router.)

> Cable from wall to router to router by ethernet cable [...]

   Eh?  Ethernet (and co-ax) cables have only two ends; they don't hop
from device to device to device.  What does "wall" mean here?  Are you
talking about a co-ax cable to the cable modem input?

   If your printer has an Ethernet port, then I'd advise using it, and
ignoring its USB port (and all Netgear ReasySHARE firmware/software).

   Not really.  If your old router can connect to the Internet through
the new modem, then I'd leave it alone, and not erase its original
(working) configuration for no good reason.

   If you were not using ReadySHARE for printing before, then there's no
reason to start now.  Especially for a network-connected printer.

   That's confusing, but if "the modem" here means "the WNDR4300
router", and the LAN-port LED does not indicate a good physical link to
the printer, then I'd worry about the Ethernet cable which you're using
(or the router LAN Ethernet port, or the printer Ethernet port).  (And
I'd still advise avoiding the USB port.)

> When print requested printer box read "Printer is not connected

   Perhaps that's because the printer is not connected.

   If you can get the router to indicate a good physical link to the
printer, then the router's Attached Devices report should show the
printer (under: Wired Devices).  When that happens, your client devices
may be able to communicate with it, too.

   Swapping cable modems should not have a big effect on a
network-connected printer.  Typically, there would be no good reason to
change anything on the router's LAN configuration, and no good reason to
reset anything.  Some folks you'll find on these forums apparently
believe that a router-settings reset is a first step, rather than a last
resort.  (Some of them also append a useless hardware inventory to their
posts.)

   Sometimes a simple Web search is easier than asking a lame question.
